The construct validity of a psychological test is assessed by a multitrait-multimethod nomothetic matrix, which means that the psychometric properties of an assessment instrument are studied with a variety of populations and in a variety of settings and weighed against a variety of other measures that purportedly assess the same construct. This concept implies that a test might have strong validity with some populations and weak validity with others, and this is the central theme of this book. In order to add to the construct validity of the Millon Clinical Multiaxial Inventory (MCMI), evidence is presented on the psychometric properties of the test with both alcohol and drug abusers. Chapter 1, Epidemiology of Substance Abuse, reviews the scope of the abuse problem, sources of data on prevalence, and costs. Chapter 2, Overview of MCMI, discusses assessing personality disorders and theory and instrumentation. Chapters 3 and 4 explain in detail the two scales of the MCMI that assess alcohol and drug abuse, both directly and indirectly, along with the psychometric properties of these scales and the ways in which they have been used to detect substance abuse and assess substance abusers. Chapter 5 integrates the research findings presented in Chapters 3 and 4 and concludes with directions for future research. The final chapter presents an annotated bibliography of all studies conducted with substance abusers using the MCMI. Supportive illustrations and tables further enhance the presentation of the MCMI scales.All values were lower than those reported in the test manual, which tested
